Diaz, prosecutors said, knew both victims and had encountered them earlier on the night of the slayings when Diaz came to the home of his girlfriend and found her and her sister sitting with the two men in Anderson’s car.

Sams said the girlfriend had a previous relationship with both victims.

“Perhaps this is a case of someone just getting tired of people messing around with his girlfriend,” Sams told jurors.

Judge Karen Simpson set a February status date for Diaz, who will face a mandatory sentence of natural life in prison, Sams said.
